Common questions about ductwork in San Antonio

Ductwork FAQ

New ductwork installation in San Antonio costs $2,000 to $6,000 for a standard home. Ductwork replacement for an existing system costs $3,000 to $8,000. Duct sealing (fixing leaks in existing ducts) costs $500 to $2,000. Costs depend on the home's size, number of vents, accessibility (attic vs. crawl space), and duct material (flexible vs. rigid metal). C.S.W. Power Solutions provides a free estimate with all costs itemized.
Signs your ductwork needs repair or replacement include uneven temperatures between rooms, high energy bills, visible duct damage or disconnections in the attic, excessive dust in the home, musty odors from vents, and ducts that are over 15 years old. Flexible ductwork degrades faster than rigid metal and should be inspected every 10 years. Poorly sealed ducts can lose 20-30% of conditioned air.
For San Antonio's hot climate, we recommend insulated rigid metal ductwork for main trunk lines and insulated flexible ductwork for branch runs. R-8 insulation is the minimum for attic ductwork in Texas. Rigid metal ducts are more durable and have better airflow, while flexible ducts are easier to route in tight spaces. All ductwork should be properly sealed with mastic or metal tape — never duct tape.
Yes. The Department of Energy estimates that leaky ducts can reduce HVAC efficiency by 20-30%. In San Antonio's extreme heat, that translates to significant energy waste. Professional duct sealing closes gaps and leaks at joints, connections, and boot connections. Most homeowners see a 10-20% reduction in energy bills after duct sealing. C.S.W. Power Solutions uses mastic sealant and metal-backed tape for permanent, code-compliant seals.
Rigid metal ductwork lasts 20 to 25 years or more with proper maintenance. Flexible ductwork typically lasts 10 to 15 years before the inner liner and insulation degrade. In San Antonio attics, where temperatures can exceed 150°F in summer, ductwork deteriorates faster. Regular inspection and maintenance extends duct life and maintains efficiency.
Yes. C.S.W. Power Solutions installs ductwork for room additions, garage conversions, and home expansions. As a licensed general contractor with in-house HVAC (TACLA 26479R), we coordinate ductwork installation with framing, electrical, and plumbing for seamless integration. We also install ductless mini-split systems for additions where extending existing ductwork is not practical.
